Splined upon the COUflR'bSlH'Li lJ ltetween the gears 25% anal 29 is a similar clutrzh collar39 W'l'liCl'L, lilw the collar 38 is provide? at ends with lugs amipteiito mate with S1111 lugs upnn the cmifmnting 0f az's. Slidahla throughthe rear end wall of the gear case are rods 1-0 and 41 provided withforks and 43, the fork 4 2 coacting with the collar 3S and the fork l3coacting with the col a1 39. In Figure 1, l have shown my improvedtransmission gearing in cmincction With a n'iotor veh le 1 lconventional design. The engine of the vehicle is indicated at l6 andthe. floor at -17. As will be observed, the gearing is an tinged in rearof the engine and is suits oly supported upon the frame of the chassisso that the power shalt may e."- tend from the engine into the gearcase. llflounted upon the floor l? of the vehicle is a base plate 4-8and pivoted upon this plate are control. levers 49 and respectively. Atits lower end the lever el is pivotally connected to the rod all whilethe lever so is pivotally connected at its lower end to the rod ell.Thus, as will be seen, the lever 4%) may he rocked rearwardly forshifting the collar 38 into engagement with the gear 26 when this gearwill be coupled to the countershatt 16 for giving low speed. ()n theother hand, by shiftin the lever -14) forwardly, the collar 18 will bemoved to engage the gear 27. This gear will then be coupled with thecountershat't for giving reverse. Similarly. the lever 50 may be rockedforwardly for shift ing the collar 39 into engagement with the gear 28For giving second speed while when said lever rocked rearwardly. thecollar 39 will he moved into engagement with the gear for givinghigrhspeed. As will he noted, all of the gears are constantly in mesh andclashing oi the gears will, when shitting from one speed to another, heaccordingly eliminated.

in Figure (S of the drawings, 1 have shown a slight modification of theinvention which relates jinivticularly to the control incchanismemployed for shitting the collars 38 and 39. In this modification. thelever 5 retained while, in lien 01' the lever 4.9. a shaft 51cn'iployed. This shaft is suitably journaled to rock about a verticalaxis and extending from the shaft is an arm 52 to which is pivotallyconnected the rear end of the rod l0. At its upper end the shalt isformed with a cross head 53 and supported by said head are pedals 54 and.35 rcspoctively. By pushing, upon thc pedal 54. the collar 38 may beshifted rcarwardiy for giving low speed while by pushing upon the pedal55 the collar may be shifted forwardly for gi ving reverse.

Having thus described the invention, what is claimed as new is:

l. A transmission gearing" including a gear case having a partitionextending from side 1 senses to side thereof bracing the gear case,shafts journaled upon the case comprising a power shaft, a driven shaftand a counter-shaft having gear connection with the power shaft, gearsfixed upon the counter-shaft, gears loose upon the driven shaftconstantly meshing with the gears of the countershat't, means secured tothe partition holding one of the gears of the driven shaft againstendwise movcn'icnt, means secured to the walls of the case holding theother of the gears of the driven shaft against endwise movement, andclutch elements mounted upon the driven-shaft to turn therewith andslidable upon said shaft to selectively engage the gears thereon.

A transmission gearing including a gear case having a partitionextending from side to side thereof bracing the gear case, shaftsjournaled thereon comprising a power shaft, a driven shaft and acountershat't having gear connection with the power shaft, gears firedon the counter-shaft, gears loose on the driven shaft meshing with the.gears of the counter-shaft, a fork secured to the partition and engagingone of the gears of the driven shaft for holding said gear againstcndwise movement, other torks serured to the case and engaging the otherof the gears oi the driven shaft for holding said otl 7r gears againstcndwise movement, and clutch elements mounted upon the driven-shaft toturn therewith and slidahlc upon said shaft to selectively engage thegears thereon.

5. la a transmission gearing, the combination of a gear case having apartition extending from side to side thereof bracing the gear case, apower shaft extendingthrough one end of the gear case terminating shortof said partition, a driven shaft extending through the opposite end ofthe gear case and journaled at one end upon the partition, acountershatt extending through the partition and journalcd at its endsupon the ends of the case as well as upon said partition. a gearconnection between the power shaft and the countershaft, gears tixed onthe countcrshal't. ears loose on the driven shaft conslantly moshingwith the gears of the countcrshaft. stationary moans coacting, with thehubs of the gears of the driven shaft llOltllllfJ such gears againstcnd- \visc movement. one of such means being carried by said partition,and clutch elements mounted upon the driven shaft to turn therewith butslidablc upon said shaft to selectively engage the gears thereof.
